toughness and ductility through the use of grain refining alloys. The Jennmar “X” grade bolts should provide better performance in mines where Stress Corrosion Cracking is evident and also in areas of high localised horizontal stresses

• The JX rock bolt profile provides superior load transfer characteristics using the unique “J” bar pattern.

• Recommended for drill hole sizes 27 – 28mm diameter without mixing devices or 35-40mm with resin mixing devices

• M24 couplers, 35mm diameter are available for use with torque tension bolts

• Various roll pin break-out torque ranges available

• Available as galvanised

• Left hand thread required for hard rock and civil installation

HAWKESBURY CABLE BOLTCABLE BOLTS

The Hawkesbury Cable Bolt is a specially designed permanent, flexible rock anchor which is capable of fully mechanized and remote installation. The anchor features a mechanical anchor and threaded head connection enabling point anchorage and pre-tensioning at the excavation site. A robust high density polyethylene sheathing not only provides excellent corrosion protection, giving the anchor a 100 year design life, but also facilitates top-down grouting.

HAWKESBURY CABLE BOLT (continued)

CABLE BOLTS

Typical ApplicationsInclude major civil engineering projects, such as tunnelling and slope stability, as well as life-of-project infrastructure in the mining industry.

Sheathing corrugations must be uniform and generally sinusoidal in shape, conforming to the following: (1) Wall thickness (w) of ducts: w > 2mm (2) Pitch of corrugations (p): 6w ≤ p ≤ 12w (3) Amplitude of corrugations (a): a > 3w The profile must not allow voids to be formed in the grout column

• Large bearing area of 450 x 450 mm

• Rolled safety edges and corners to eliminate handling cuts

• Re-inforced rolls around the perimeter for extra rigidity

• Used in combination with a lightweight bearing plate, ideal for rib confinement

• Used in conjunction with a SuperStrand plate, ideal for soft roof to reduce likelihood of cutting mesh upon loading

Features

• For pinning mesh against the rock face over top of pre-installed rock bolts

• Welded nut of any size to thread onto existing installed rock bolts

• 200mm round plate to aid spinning the plate against mesh, no corners to catch in the wires

• Extruded extra height to accommodate the standard tail length of an installed bolt, allowing the mesh to be pushed tight against the rock face

• 3mm thick plate for extra strength

• Good for pinning rock fall netting over installed dynamic ground support

Features• The Sorrich “Clip Up” hook has been developed

for underground application and designed to hold four inch (110mm) Polyurethene Pipe

• Load rated hanger to 800kg WLL

• The diameter of each separate hook is 120mm, allowing enough room to easily slide “poly” inside the circumference of each hook and just enough room for the poly pipe to be held firm inside the hook to reduce movement. Each 4-inch poly line are then locked in place by our patented locking system, which integrates with the Minsup clip for quick and easy installation. The “Clip Up” is made from 6mm galvanised mild steel for strength and to prevent rusting in normal underground environments

• The top is an open 2-inch (66mm) hook for possible temporary 2-inch poly pipe or for use with power or pump cable, which prevents tangles amongst other lines.

• The backside of the hook has been designed to be capable of clipping back to the mesh or rock bolts with a simple “D” shackle when hanging in the ‘’shoulders”.

• This product is the only one of its kind on the market and it is the safest, fastest and neatest way to install poly pipe.
